Simulation of Monorail Train Dynamics

Program package Universal Mechanism includes a specialized module UM Monorail Train for analysis of 3D dynamics of both single vehicle and trains. The module includes additional tools integrated into the program kernel.

UM Monorail Train contains the following main components: 

  • tools for generation and visualization of guideway structure (bridge) geometry;
    tools for generation and visualization of guideway structure (bridge) geometry
  • tools for generation and visualization of guideway roughness (irregularities);tools for generation and visualization of guideway roughness (irregularities)
  • mathematical models of tire forces (tire/road contact forces): Fiala tire model, Pacejka magic formula, tabular data;mathematical models of tire forces
  • model of a flexible monorail beam;
  • set of typical dynamic experiments.

UM Monorail Train allows the user to solve the following problems:

    • estimation of vehicle vibrations due to irregularities;

estimation of vehicle vibrations due to irregularities

    • estimation of vehicle dynamic performances on curving;
      estimation of vehicle dynamic performances on curving
    • parametric optimization of vehicle elements according to various criteria;
    • longitudinal forces and vibrations for trains.
    • calculation of natural frequencies and normal modes of a flexible monorail beam and train
